In a previous post I mentioned I am shutting down. My intent was to coat the hopper on the KA-2 with bedliner. Now that I have in vacuumed out and taken off the boiler I can get a good look at it. The bottom is still shiny metal the side have surface rust, probably because I mist the coal with a garden sprayer when filling the hopper.So maybe bedliner is over kill? I have oil based primer on my shelf and my thought is prep the metal and give it a few coats of primer and maybe a top coat.Thoughts?Thanks

I'd do the primer. I agree bedliner would be overkill. I use Rustoleum rusty metal primer on the lower section of my auger which is down in coal that is damp at least part of the season. It seems to hold up well.
